Wear Platform shoes?

All you can do is accept the height you are. If you are a man you may still grow a bit more but if you haven't in a while you may be done. Some guys continue growing into their early twenties, though most are done at your age. If you are a woman, you are certainly done growing.

Focus on something important like your intelligence and character instead of things you cannot control.

That is 20% more height than you are now. At your age extremely doubtful.

There are extremely painful and expensive surgeries that may give you a few more centimeters, but nowhere near the height you want to gain.

Your height is determined by your genes. There is really nothing you can do to make yourself taller, other than Smoothy's suggestion, wearing platform heels.

You'll have to accept the height you are.

While you may still grow a few CM. you will not grow that much more. No magic pills, exercise or anything. You will have to learn to accept who you are.

I think that there are available growth enhancer. I think you will still grow. Eat vegetables and fruits.
